BACKGROUND Technical Field

The disclosure relates to a system, and particularly relates to an operating system with automatic login mechanism and an automatic login method.

Description of Related Art

With the popularity of various computer devices, the computer devices have been widely used to handle personal affairs, business affairs or industrial affairs. In this regard, the computer device may store highly private or highly confidential information, so ordinary computer devices usually have a login mechanism. The user must enter a correct user account and a login password to login to the computer device for use. However, due to phishing programs and computer viruses are highly rampant, the login mechanism using the login password to authenticate a user can no longer provide sufficient security for the computer device. For example, once the user is incautious, a backdoor program (for example, a Trojan horse) is planted in a computer very easily. As a result, the login password for the computer is logged and stolen by a malicious person such as a hacker. Personal data or confidential information stored on the computer further leaks consequently, or even the control right of the computer is acquired by the malicious person. Although, some improved login mechanisms have been proposed, such as a built-in fingerprint login mechanism in the computer or using a mobile phone to connect to the computer for Bluetooth communication verification. However, when the user changes the computer, the user must re-enter complicated fingerprint registration, or when the communication quality of the mobile phone and the computer is poor or cannot support Bluetooth communication authentication, it is easy to cause the user to fail to log in the computer effectively. Therefore, regarding how to provide a secure login function and a convenient login mechanism, solutions of several embodiments are provided below.

SUMMARY

The disclosure is directed to an operating system with automatic login mechanism and an automatic login method, and can provide an effectively automatic login operation.

An operating system with automatic login mechanism of the disclosure includes a first electronic device, a second electronic device and a server device. The second electronic device is coupled to the first electronic device, and comprising a biometric sensor. The server device is coupled to the first electronic device and the second electronic device. When a login event of the first electronic is triggered, the first electronic device sends a login request to the second electronic device directly or via the server device, so that the second electronic device performs a biometric verification by the biometric sensor according to the login request. When the biometric verification is passed, the second electronic device sends a first login credential to the first electronic device directly or via the server device, so that the first electronic device performs an automatic login operation of the first electronic device according to the first login credential.

An automatic login method of the disclosure includes the following steps: sending a login request to the second electronic device directly or via the server device by the first electronic when a login event of the first electronic is triggered; performing a biometric verification by the second electronic device according to the login request; sending a first login credential to the first electronic device directly or via the server device by the second electronic device when the biometric verification is passed; and performing an automatic login operation of the first electronic device by the first electronic device according to the first login credential.

Based on the above, according to the operating system with automatic login mechanism and the automatic login method of the disclosure, the user can log in to an electronic device by the biometric verification on another electronic device to achieve the password-free login function.

Referring to FIG. 2 and FIG. 3 , the operation system 200 includes a first electronic device 210, a first electronic device 210, and a server device 230. The first electronic device 210 may be a notebook computer, the second electronic device 220 may be a mobile phone with fingerprint verification function, and the server device 130 may be a cloud server. The first electronic device 210, the second electronic device 220, and the server device 230 may have the internal device features of the first electronic device 110, the second electronic device 120, and the server device 130 of FIG. 1 . The operation system 200 may perform the following steps S301 to S310 to implement the registration operation.

In step S301, when a registration event of the first electronic device 210 is triggered, the first electronic device 210 receives a registration information 201 including a user account and a login password. The first electronic device 210 may display a login screen for the user 240 to input the user account and the login password, and the first electronic device 210 may communicate with the server device 230 through an internet. In step S302, the first electronic device 210 may send a registration request 202 to the identity management module of the server device 230. In step S303, the server device 230 may send a registration token 203 to the first electronic device 210 according to the registration request 202. The registration token 203 is provided by the identity management module of the server device 230. Then, in step S304, the first electronic device 210 may generate a first login credential 204 and a second login credential for encrypting and decrypting the login password. In the embodiment of the disclosure, the second electronic device 220 generates a public key and a private key according to an asymmetric encryption mechanism, such as a public key infrastructure (PKI), and the second electronic device 220 provides the public key and the private key to the first electronic device 210. In the embodiment of the disclosure, the first electronic device 210 stores the private key into the first login credential 204, and encrypts the login password to serve as the second login credential by the public key. The first electronic device 210 stores the second login credential, and transmits the first login credential 204 to the second electronic device 220, so that the second electronic device 220 can store and protect the private key.

In step S305, the first electronic device 210 may store the second login credential. In step S306, the first electronic device 210 may send the registration token 203 and the first login credential 204 to the second electronic device 220. The registration token 203 and the first login credential 204 are provided by the credential management module of the first electronic device 210, and the registration token 203 will be linked reference to a first login credential 204. In step S307, the second electronic device 220 may perform the biometric verification 205 (fingerprint verification) through a biometric sensor (fingerprint sensor) of the second electronic device 220. The second electronic device 220 may display a user interface including a biometrics verification request screen to prompt the user 240 to perform the biometric verification 205 through the biometric sensor.

In step S308, when the biometric verification is passed, the second electronic device 220 may generate a registration data 206 for the first login credential 204, and send the registration data 206 and the registration token 203 to the server device 230. The registration data 206 is generated by the credential management module of the second electronic device 220, and the credential management module of the second electronic device 220 may associate the first login credential 204 with biometric verification data of the biometric verification. In step S309, the server device 230 may send the registration data 206 and a registration confirmation 207 to the first electronic device 210 according to the registration token 203. The identity management module of the server device 230 may compare the registration token 203 sent to the first electronic device 210 and the registration token 203 received from the second electronic device 220 are same registration token to confirm whether the registration is successful. In other embodiments of the disclosure, the server device 230 further receives a user account sent from the first electronic device 210, and the server device 210 sends the registration confirmation 207 to the first electronic device 210 according to the registration token 203 and whether the user account matches a pre-stored user account.

In step S310, the first electronic device 210 may merge and store the registration information 201, the second login credential 204, and the registration data 206 to a data set according to the registration confirmation 207. Therefore, the user 240 can effectively register on the first electronic device 210, and the first electronic device 210, the second electronic device 220 and the server device 230 may also store the registration data 206 respectively. More importantly, the registration information 201 including the user account and the login password be securely stored in the first electronic device 210, and the registration information 201 will not be sent to the second electronic device 220 and the server device 230.

It should be noted that, when user 240 executes the login operation, the second electronic device 220 generates a new public key and a new private key, and transmits the first login credential 204, the new public key and the new private key to the first electronic device 210. Then, the first electronic device 210 uses the private key stored in the first login credential 204 to decrypt the second login credential to obtain the login password. After the first electronic device 210 successfully logs in, for example, the operation system of the first electronic device 210 by the login password, the first electronic device 210 stores the new private key into a new first login credential, and encrypts the login password by the new public key to serve as a new second login credential. The first electronic device 210 stores the new second login credential, and transmits the new first login credential to the second electronic device 220, so that the second electronic device 220 stores and protects the new private key. In other words, since the second electronic device 220 changes the public key and the private key after each login event, the login password can be effectively protected. In other embodiments of the disclosure, the above public key and the above private key may be generated by a symmetric encryption mechanism, so that the first electronic device 210 uses a secret key to encrypt the login password into the first login credential 204, and the first electronic device 210 stores the secret key into the second login credential. Moreover, the second electronic device 220 also changes the secret key after each login event, so as to effectively protect the login password.

FIG. 4 is a communication schematic diagram illustrating an operating system that performs automatic login according to an embodiment of the disclosure. FIG. 5 is a flowchart illustrating an automatic login method according to an embodiment of the disclosure. Referring to FIG. 4 and FIG. 5 , after the registration operation of the above embodiment, the operation system 200 may perform the following steps S510 to S560 to implement the login operation. In step S510, the first electronic device 210 receives a login information 401 including a user account from the user 240, and determines whether the user account of the login information 401 matches the user account of the registration information (for example, the registration information 201 of FIG. 2 ), so as to send the login request 402. The login request 402 may be provided by the major logic control module of the first electronic device 210. In the embodiment of the disclosure, when a login event of the first electronic device 210 is triggered, the first electronic device 210 may try to communicate with the second electronic device 220 through the wireless communication, or to communicate with the server device 230 through the internet. It should be noted that, the first electronic device 210 may be design to send the login request 402 to at least one of the second electronic device 220 and the server device 230. In the embodiment of the disclosure, if the first electronic device 210 communicates with the second electronic device 220 before communicating with the server device 230, or the first electronic device 210 is design to send the login request 402 to the second electronic device 220, then in step S521, the second electronic device 220 receives the login request 402 from the first electronic device 210 directly. However, in other embodiments of the disclosure, if the first electronic device 210 communicates with the server device 230 before communicating with the second electronic device 220, or the first electronic device 210 is design to send the login request 402 to the server device 230, then in step S522, the server device 230 receives the login request 402 from the first electronic device 210 through the internet. In step S523, the server device 230 sends a login notification 403 according to the login request 402 to the second electronic device 220 through the internet. The major logic control module of the server device 230 may receive the login request 402 from the first electronic device 210, and then generate and transmit the login notification 403 to the second electronic device 220 according to the login request 402. In other words, the first electronic device 210 may send the login request 402 to the second electronic device 220 directly or via the server device 230.

In the embodiment of the disclosure, the major logic control module of the second electronic device 220 may request the second electronic device 220 to drive the biometric sensor for biometric sensing according to the login request 402 or the login notification 403. In step S530, the second electronic device 220 performing the biometric verification 404 according to the login request 402. In the embodiment of the disclosure, the second electronic device 220 may display a user interface including a biometrics verification request screen to prompt the user 240 to perform the biometric verification 404 (fingerprint verification) through the biometric sensor (fingerprint sensor). In step S540, when the biometric verification 404 is passed, the second electronic device 220 may send the first login credential 405. The first login credential 405 may be provided by the credential management module of the second electronic device 220 according to the biometric verification 404. In the embodiment of the disclosure, the first login credential 405 is a passwordless credential as the above embodiments of FIG. 2 and FIG. 3 , but the present disclosure is not limited thereto. It should be noted that, the second electronic device 220 may be designed to send the first login credential 405 to at least one of the first electronic device 210 and the server device 230. In the embodiment of the disclosure, if the second electronic device 220 is designed to send the first login credential 405 to the first electronic device 210, then in step S551, the first electronic device 210 receives the first login credential 405 from the second electronic device 220 directly. However, in other embodiments of the disclosure, if the second electronic device 220 is designed to send the first login credential 405 to the server device 230, then in step S552, the server device 230 receives the first login credential 405 from the second electronic device 220 through the internet. In step S553, the server device 230 sends the first login credential 405 to the first electronic device 210 through the internet. The major logic control module of the server device 230 may receive the first login credential 405 from the second electronic device 220, and then transmit the first login credential 405 to the first electronic device 210. In other words, when the biometric verification 404 is passed, the second electronic device 220 sends the first login credential 405 to the first electronic device 210 directly or via the server device 230.

In step S560, the first electronic device 210 performs an automatic login operation of the first electronic device 210 according to the first login credential. In the embodiment of the disclosure, the first electronic device 210 uses the private key (or the secret key) contained in the first login credential 405 to decrypt the second login credential to obtain the login password. Thus, the first electronic device 210 uses the login password to perform the automatic login of the first electronic device 210. Therefore, in the embodiment of the disclosure, the user 240 only needs to input the user account into the first electronic device 210 to trigger the login event, and the user 240 does not need to input any password during the login operation. The user 240 can safely, quickly, and automatically login to the first electronic device 210 through the biometric verification 404 of the second electronic device 220.

In addition, when the biometric verification 404 is passed, the second electronic device 220 also sends a new public key and a new private key (or a new secret key) to the first electronic device 210 directly or via the server device 230. After the step S560, the first electronic device 210 may encrypt the login password by the new public key to serve as a new second login credential, and store the new private key into a new first login credential. The first electronic device 210 may store the new second login credential, and transmit the new first login credential to the second electronic device 220 directly or via the server device 230.

FIG. 6 is a communication schematic diagram illustrating an operating system that performs automatic login according to another embodiment of the disclosure. FIG. 7 is a flowchart illustrating an automatic login method according to another embodiment of the disclosure. Referring to FIG. 6 and FIG. 7 , after the registration operation of the above embodiment, the operation system 200 may perform the following steps S710 to S780 to implement the login operation. In step S710, the first electronic device 210 receives a login information 601 including a user account, and determines whether the user account of the login information 401 matches the user account of the registration information (for example, the registration information 201 of FIG. 2 ), so as to send the login request 602. The login request 602 may be provided by the major logic control module of the first electronic device 210. In the embodiment of the disclosure, when a login event of the first electronic device 210 is triggered, the first electronic device 210 may try to communicate with the second electronic device 220 through the wireless communication, and to communicate with the server device 230 through the internet. It should be noted that, comparing with the above embodiment of FIG. 4 , the first electronic device 210 may be designed to only send the login request 602 to the server device 230. That is, considering the security of data transmission, under certain operating scenarios, the security of data transmission via network communication may be higher than that of wireless communication. Thus, in step S720, the server device 230 receives the login request 602 from the first electronic device 210 through the internet. In step S730, the server device 230 sends a login notification 603 according to the login request 602 to the second electronic device 220 through the internet. The major logic control module of the server device 230 may receive the login request 602 from the first electronic device 210, and then generate and transmit the login notification 603 to the second electronic device 220 according to the login request 602.

In the embodiment of the disclosure, the major logic control module of the second electronic device 220 may request the second electronic device 220 to drive the biometric sensor for biometric sensing according to the login notification 603. In step S740, the second electronic device 220 performing the biometric verification 604 according to the login notification 603. In the embodiment of the disclosure, the second electronic device 220 may display a user interface including a biometrics verification request screen to prompt the user 240 to perform the biometric verification 604 (fingerprint verification) through the biometric sensor (fingerprint sensor). In step S750, when the biometric verification 604 is passed, the second electronic device 220 may send the first login credential 605. The first login credential 605 may be provided by the credential management module of the second electronic device 220 according to the biometric verification 604. In the embodiment of the disclosure, the first login credential 605 is a passwordless credential as the above embodiments of FIG. 2 and FIG. 3 , but the present disclosure is not limited thereto. It is should be noted that, comparing with the above embodiment of FIG. 4 , the second electronic device 220 may be design to only send the first login credential 605 to the server device 230. Thus, in step S760, the server device 230 receives the first login credential 605 from the second electronic device 220 through the internet. In step S770, the server device 230 sends the first login credential 605 to the first electronic device 210 through the internet. The major logic control module of the server device 230 may receive the first login credential 605 from the second electronic device 220, and then transmit the first login credential 605 to the first electronic device 210.

In step S780, the first electronic device 210 determines whether to perform the automatic login operation according to the first login credential 605 and whether the second electronic device 220 is within a preset range. In the embodiment of the disclosure, the credential management module of the first electronic device 210 may read registration data (for example, the registration data 206 of FIG. 2 ) to read the second login credential (for example, the second login credential previously stored in the first electronic device 210), and may determine whether the first login credential 605 matches (or equals to) the second login credential to verify the first login credential 605. Furthermore, the first electronic device 210 may further collect the wireless communication signal information 606 (for example, a Bluetooth communication signal or a Wi-Fi communication signal) of the second electronic device 220 to determine the positioning coordinate of the second electronic device 220 (for example, obtained through a global positioning system (GPS) or a location based service (LBS)), and calculate a distance between a first positioning coordinate of the first electronic device 210 and the second positioning coordinate of the second electronic device 220. Thus, the first electronic device 210 may determine whether the second electronic device 220 is within the preset range according to whether the distance between a first positioning coordinate of the first electronic device 210 and the second positioning coordinate of the second electronic device 220 is less than a preset distance. However, in other embodiments of the disclosure, the preset range may be a farthest distance that the first electronic device 210 can receive the wireless communication signal of the second electronic device 220.

Therefore, the user 240 only needs to input the user account into the first electronic device 210 to trigger the login event, and the user 240 does not need to input any password during the login operation. Moreover, since the first electronic device 210 of the embodiment will only perform the automatic login operation when the second electronic device 220 is close to the first electronic device 210 and first login credential 605 is verified, the operating system 200 can prevent the second electronic device 220 from being stolen and perform remote login. The user 240 may hold the second electronic device 220 and approach the first electronic device 210 to safely, quickly, and automatically login to the first electronic device 210 through the biometric verification 604 of the second electronic device 220.

In addition, when the biometric verification 604 is passed, the second electronic device 220 also sends a new public key and a new private key (or a new secret key) to the first electronic device 210 via the server device 230, and the first electronic device 210 may encrypt the login password by new public key to serve as a new second login credential, and store the new private key into a new first login credential. The first electronic device 210 may store the new second login credential, and transmit the new first login credential to the second electronic device 220 via the server device 230.

In summary, the operating system with automatic login mechanism and the automatic login method of the disclosure are capable of providing safely and quickly login mechanism. The user may perform the login operation on an electronic device to login to the electronic device through the biometric verification of another electronic device, wherein the user only needs to input the user account into the electronic device to trigger the login event, and the user does not need to input any password to the electronic device and the another electronic device during the login operation. Therefore, the operating system with automatic login mechanism and the automatic login method of the disclosure can provide a safely, quickly, and automatically password-free login function.
